Project Abstract 

Geothermal resources are classified as renewable, but are a combination of an energy current and vast stored energy. This project focussed on the Reykjanes high-temperature geothermal system on the tip of SW-Iceland, where a 100 MWe power plant started operation in 2006. The associated production has caused drastic changes in reservoir conditions. The purpose of the project was to evaluate the renewability of the Reykjanes geothermal system under current utilization, which was done through compilation of available reservoir monitoring data, and collection of micro-gravity and geodetic data. Consequently these data were jointly interpreted, partly through modelling. The results do e.g. indicate that during the period 2008 – 2010 the renewal of reservoir fluid through recharge was of the order of 30 – 50%.
